RHBA-2017:2432 - kexec-tools bug fix update

Synopsis

kexec-tools bug fix update

Type/Severity

Bug Fix Advisory None

Topic

Updated kexec-tools packages that fix two bugs are now available for Red Hat Enterprise Linux 7.3 Extended Update Support.

Description

The kexec-tools packages contain the /sbin/kexec binary and utilities that together form the user-space component of the kernel's kexec feature. The /sbin/kexec binary facilitates a new kernel to boot using the kernel's kexec feature either on a normal or a panic reboot. The kexec fastboot mechanism allows booting a Linux kernel from the context of an already running kernel.

This update fixes the following bugs:

  • When the "fence_kdump_nodes" option was set and nodes were referenced by IP address, kdump attempted to send fence_kdump notifications to the same node where the crash occurred and waited for a response indefinitely. As a consequence, generating the kdump file was unsuccessful and led to an infinite loop. This update excludes the IP address of the local node from the list of IP addresses to which kdump sends the fence_kdump notifications. As a result, generating the kdump file can now finish successfully, and the described problem no longer occurs. (BZ#1460212)

  • Previously, a bug in the makedumpfile tool sometimes affected large memory IBM Power Systems. As a consequence, makedumpfile failed with the "unhandled sig 11" error in the kdump kernel when saving the vmcore on IBM Power Systems. This update fixes the kexec-tools, and the described problem no longer occurs. (BZ#1463537)

Users of kexec-tools are advised to upgrade to these updated packages, which fix these bugs. The system must be rebooted for this update to take effect.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.
